Good Day,
I have a question about C# Express regarding it's legality for commercial use.
My family is running a small business and is need of a Sales and Inventory system which I can provide. I'm planning to use both C# express and MS SQL Express for developing the said system.
Is it legal to use it as such? Or it is limited for "educational" purposes only.
Thanks!

A) I think it's OK
B) Even if you weren't allowed to use C# Express to produce commercial apps you could still compile with the command-line C# compiler.
C) I installed SQL Server Express on the HR Director's computer and Microsoft hasn't come around and kicked in the door (yet).

Bill won't come kicking your door. I found this on their FAQ Site.
4. Can I use Express Editions for commercial use?<br />
Yes, there are no licensing restrictions for applications built using the Express Editions.

Both are fine. They were released to compete with other totally free products and to provide a path to the full versions where needed. But, there is no limit on their use.

As the others have said, you can use both for commercial use. Have done so for a few clients and all has been good.

I have an application written in C# , and I want the users to run it from the server ( windows 2003 ) without having that application installed on each and every machine using it , Just from the server . So the user has to log to the server only to be able to run it this application .
is that possible , any Ideas how to do it ?
Regards
Dean

A server will just do this, you can either run it on the server ( using remote desktop ), or have a shortcut to the exe on the server and run it locally.

Yes I know that you have to put it on the desktop as a shortcut from the server and run it locally on each user machine , but the application does not run that way , an exception is thrown , also the more users run the application at the same time the slower it gets . Oracle has a concept of "Application server " like a web server but used for forms based application .

I have created a similar application. I used the publish feature in VS2005 (not sure if exists in 2003)
Look at the publish tab of the project properties. There should be a publish wizard that will allow you to publish the application directly to the server location.
This helps get around a lot of the permission level problems. There is also an option to have a running application to check the server for updates. This can create problems if it is linked to your PC and not the server location. I disabled this for my application.
This creates a deployment manifest method for launching an application. The end user just has to copy the shortcut created by the publish wizard to their desktop and it will launch a local version of the app from the server.
Hope this helps.

That's a different thing. The Publish feature creates a ClickOnce installer for your application. No matter whether you have an icon on your Start menu or not, the application is installed on the local machine, and everytime you run it (by going to the .application URL or clicking the icon) it checks for updates in the server. But the app is actually installed in the client PC.
And no, it's a .NET 2.0 feature so it doesn't exist in VS.NET 2003.

Thanks for the clarification on this Luis,
For my deployment I selected "The application is available online only". The app does run on the local PC but doesn't get installed there.
If you remove the app on the server then it will not run on the local PC.

Actually the app *is* installed on the local PC, but no icon is created on the start menu. It needs to be downloaded so it can be run.
Check in C:\Documents and Settings\youruser\Local Settings\Application Data\Microsoft\Apps\2.0 (the path is something like that in XP -- I have Vista and I couldn't find the path here).
I have not verified it, but I believe that if you can somehow get the .application file on your publish server, it will run your application even if you don't have a connection to the server. That's actually the shortcut gets in the Start menu when the app is installed for offline use: an .application file.
But theory aside, I think that's a great solution for what you need, since I don't think users will go hunting for you app's EXE to run it.

If you remove the app on the server then it will not run on the local PC.
If you make a change and re-publish then the remote users just close the app and re-open and it will launch the latest version.

As Christian suggested, installing it on a server and using Remote Desktop to login and run it is an option. If you want more than two users, you'll need to set up Terminal Services on your server (and have some good hardware resources -- a lot of RAM).
Running it of the network with a shortcut could also work, but usually it will run with limited security permissions (from the internet zone o intranet zone and not full trust). You're getting an exception because the app is trying to do something that is not allowed.

Hi,
There is a form thas is mdi container. That form also contains one button. When a MdiChild is displayd, I can see gray MdiClient area, button and Mdi Child form too. But the button is above the Mdi Child form when they intersect. I'd like to switch the order and when the Mdi Child form comes above the button, the button will be behind the child form instead of in front of like default.
any ideas?
thanx

What is the laregest byte array one can possible allocate?
byte[] ba = new byte[i];
can i be 64-bit?
Is the answer different on a 32-bit architecture than on a 64-bit architecture?

Knowing perhaps?

But as Richard Feynman was fond of saying, don't rely on authority. Perform the experiments yourself and see the evidence for yourself. So long as your knowledge came from your own efforty, your willingness to try, then great. Otherwise, how do you really know? The authority could be lying or simply mistaken.

My point exactly.
I'd also refer to Edison and his 10000 ways that don't work.
As I say, "You learn more from your mistakes than from getting it right the first time."

it is just that my machine doesn't have more than 2 GB of RAM, so I relied on others who have huge memory space to test it out...
